[DOCS] Mouse Events on SVG Elements

[markwilx]

This is a fantastic library. Thank you for contributing it!

Describe the bug
I am attempting to register mouse events on individual SVG elements in order to create click-and-drag function. Mouse events "clickEvent" and "doubleClickEvent" are registering on svg-container but not on individual SVG elements, such as svg-circle.

To Reproduce

1. Create an svg-circle HTML tag with mouse event listeners, such as the following:
   <svg-circle diameter=25 color="#FF0000" x=450 y=50 [classes]="classesCir"
(clickEvent)="setToken($event)"
(doubleClickEvent)="pickupToken($event)"
></svg-circle>
2. Create event listeners, such as the following"
   setToken(evt) {
const fid = id + "setToken(): ";
console.log(fid);
}

pickupToken(evt) {
const fid = id + "pickupToken(): " + JSON.stringify(evt);
console.log(fid);
}
3. Execute the code and click on the SVG Circle. Note there is no output in the console.

I expect this may be a documentation error. For svg-circle, the demo and documentation at:
https://vvaldersteins.github.io/ngx-svg/home
indicate that clickEvent and doubleClickEvent are parameters of svg-circle.

But the GitHub documentation at:
https://github.com/vvaldersteins/ngx-svg#circle
does not indicate that clickEvent and doubleClickEvent are parameters of svg-circle.

Expected behavior
Registered mouse events occurring on the individual SVG elements should be handled.

Additional context
From other bug reports, it appears that SVG.js events can be referenced in ngx-sgv, such as these:
https://svgjs.com/docs/3.1/events/
Are these passed through ngx-svg?

Best,
Mark

Update: I attempted using Renderer2 to register an event listener with an svg-circle element, following the guidance on this website:
https://www.language-diary.com/2018/02/angular-event-listener-using-renderer2.html
(refer to #2, "Using Renderer2" for details).

I was unable to register an event listener for objects outside the svg-container, but failed to trigger any events on objects inside the svg-container using this method.
